在新教材实施这几年来,有关“约数”和“因数”的讨论,一直就没有停止过。有的说新教材改的不好,因为它给学生的学习带来了不必要的混淆:有的说它改的好,因为它减轻了学生的学习负担。众说纷纭,莫衷一是。教师教学用书上说:“为了克服同一单元内概念多而集中、抽象程度过高的现象,新教材中删去了”整除“的数学化定义,并把老教材中的‘约数和倍数’改为‘因数和倍数’,教材中就不再出现‘整除’、‘约数’等概念了”。那么,“约数”改为“因数”是否真 In the past few years since the implementation of the new textbook, discussions on “divisor ” and “factor ” have not stopped. Some say that the new textbook is not good because it introduces unnecessary confusion to students ’learning: Some say it is better because it lightens students’ learning burden. Different opinions, incomprehensible. Teacher teaching book said: “In order to overcome the phenomenon of the concept of more and more concentration of the same unit, the degree of abstract is too high, the new text” “divides ” mathematical definition, and the old teaching material ’ And multiples’ to ’factors and multiples’, there is no longer any concept of’ divisibility ’or’ divisor ’in the textbook. Then, “divisor ” to “factor ” is true
